New Wii features: Message Board & Play History

It's not holographic projection, but it'll let you "email" with your Wii. Nintendo sheds light on new features:

Message Board

• Stores user achievement data and shares it will other users of that console

• Integrates with games to alert players of important events; e.g. "Concert next Saturday in town" (Animal Crossing)

• Utilizes date sorting and calendar integration

• When connected to the internet, can be linked to other consoles' Message Boards to exchange notes, data, screenshots, etc. (in other words: simplified email client)
  

• Compatible with mobile phones

Play History

• Data collection function, which cannot be cleared

• Compiles total amount of playtime (and possibly other stats) for every game played

• Doubles as a monitoring system for parents wanting to keep a watchful eye on their kids' gaming habits

• Will be used by Nintendo (with user consent) to pool data into useful statistical categories; i.e. "most played game of the year"
